Way too many enemies have exploding acid arrows and fire bombs. There should be a proper Goblin Alchemist or Arsonist that would use Alchemists fire.

Where are the basic fodder goblins with low HP? Let Wizards feel useful when they drop 4 of them with Sleep. Or martial classes killing them in one hit. I don't want level scaled enemies that mean all enemies become the same.

I definitely agree tabletop rules should be altered where they don't work for a CRPG. But so far only the changes to reactions fit that bill.

I would actually prefer to first play with 100% accurate 5e rules and then consider if monsters need to be beefed up or if combat is so boring we need explosives and surfaces.
